At some point during the serialization process GWT is calling getClass() on your method return value which always resolves to the runtime class. Thats just how getClass() in Java works. I don't think you can change that behavior of GWT-RPC. If I give you an instance of type Object how would you know that you only have to serialize a specific super class of the runtime type of that instance? Thats probably only possible by searching for specific annotations that contain that information. GWT-RPC does not have such annotations.
A somewhat similar question is: https://groups.google.com/d/msg/google-web-toolkit/OxuDRkJGFDE/jQd_V0aYzaYJ You can probably do the same here. Make Subtype a shared class with a super-source version for GWT. The super-source version would be empty and just extend Type. The CustomFieldSerializer for Subtype would now only read/write the Type variables during de-/serialization. -- J. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
